AI Technical Summary
Existing compressed air-water hybrid snowmaking machines suffer from poor snow quality and low snow production rate due to the influence of direct sunlight and ambient temperature during the droplet condensation process.
The high-pressure water and high-pressure air in the dual-fluid nucleator are mixed and then a low-temperature environment is provided by the snow-condensing screen and cooling components in the snow-condensing component. This allows the water mist to evaporate, condense and crystallize rapidly, forming clusters or flocculent snow crystals, which improves snow quality and increases snow yield.
It improves the quality and snow production rate of snow, reduces dependence on ambient temperature, and saves on snowmaking costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of snowmaking system technology, and in particular to a snowmaking machine terminal auxiliary device and a snowmaking system. Background Technology
[0002] In recent years, with the development of China's ice and snow industry, more and more indoor and outdoor ski resorts have sprung up. Northern regions, with their lower temperatures, are primarily suitable for outdoor ski resorts, while southern regions, with their higher temperatures and humidity, are mainly developing indoor ski resorts. Outdoor ski resorts are also being built in some high-altitude areas in the south where temperature and humidity are more suitable. The development of ski resorts is inseparable from snowmaking machines, with the most commonly used type being the compressed air-water hybrid snowmaking machine.
[0003] The working principle of a water-air mixing snowmaking machine is to mix high-pressure water from a high-pressure water pump with high-pressure air from an air compressor at the nozzle of a two-fluid nucleator. Natural evaporation and the volume expansion of the air exiting the nozzle carry away heat, causing the droplets to condense into ice crystals. Because the water droplets atomized by the two-fluid nucleator are very small, generally on the order of tens of micrometers, these small ice crystals, while drifting in the air, are affected by direct sunlight and ambient temperature, melting back into smaller water droplets as they fall to the ground. This results in poor snow quality (larger ice crystals), reducing snow quality and snow production rate.
[0004] Therefore, there is an urgent need to design a snowmaking machine terminal auxiliary device and snowmaking system to solve the above technical problems. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0043] Example 1
[0044] This embodiment provides a snowmaking machine terminal auxiliary device that can improve snow quality, increase snow production rate, and save costs.
[0045] like Figure 1 As shown, the snowmaking machine's terminal auxiliary device mainly includes a dual-fluid nucleator 100, a snow-condensing component 200, and a cooling component 300. The dual-fluid nucleator 100 contains both high-pressure water and high-pressure air. The snow-condensing component 200 includes a housing 210 and a snow-condensing screen 220, which is disposed on the inner wall of the housing 210. The housing 210 has an inlet and an outlet that communicate with each other. The inlet is connected to the dual-fluid nucleator 100, and the outlet is configured to eject snow crystals. The cooling component 300 is connected to the housing 210.
[0046] Based on the above design, in this embodiment, the high-pressure water and high-pressure air in the dual-fluid nucleator 100 can mix at the nozzle of the dual-fluid nucleator 100 to form a water mist that is sprayed into the snow-condensing component 200. The cooling component 300 provides a low-temperature environment for the snow-condensing component 200. The temperature of this low-temperature environment is below the freezing point, which allows the water mist sprayed into the shell 210 of the snow-condensing component 200 to evaporate, condense, and crystallize rapidly. The water then adheres to and collects through the snow-condensing screen 220 on the inner wall of the shell 210, forming clusters or flocculent snow crystals. Finally, these snow crystals are ejected from the shell 210 by the pressure of the high-pressure air from the dual-fluid nucleator 100 itself. The snow-condensing screen 220 in the snow-condensing component 200 allows for the formation of larger snow crystals, thereby improving snow quality, increasing snow production rate, and saving costs.
[0047] In this embodiment, the temperature of the high-pressure water is set to 0℃-2℃, and the temperature of the high-pressure air is set below the freezing point (i.e., below 0℃). This allows the high-pressure air and high-pressure water to mix, enabling snowmaking above 0℃ in an environment where the ambient temperature can exceed the freezing point. This reduces dependence on ambient temperature and improves flexibility and applicability. Furthermore, it increases the snow production rate of the snowmaking machine's terminal auxiliary device in environments above 0℃, reduces the cooling requirements of indoor snow farms without a cold source, and achieves energy conservation.
[0048] Optionally, the dual-fluid nucleator 100 in this embodiment is a conventional component in the art. Therefore, the structure and working principle of the dual-fluid nucleator 100 will not be described in detail in this embodiment.
[0049] like Figure 1 As shown, in this embodiment, the snow-condensing screen 220 has multiple mesh openings arranged in an array, which enhances the adhesion and aggregation of snow crystals, facilitates the formation of larger snow crystal clusters, improves snow quality, and increases snow yield.
[0050] Optionally, in this embodiment, the snow-condensing screen 220 is welded to the inner wall of the housing 210 or integrally formed, which improves the stability and reliability of the connection between the housing 210 and the snow-condensing screen 220, and reduces or avoids the risk of the snow-condensing screen 220 falling off.
[0051] like Figure 1 As shown, in this embodiment, the snowmaking machine terminal auxiliary device further includes a water mist cryogenic mixing component 400. The water mist cryogenic mixing component 400 has a water mist cryogenic mixing chamber, a first port 410, a second port 420, and a third port 430. The first port 410, the second port 420, and the third port 430 are all connected to the water mist cryogenic mixing chamber. The first port 410 is connected to the dual-fluid nucleator 100, the second port 420 is connected to the cooling component 300, and the third port 430 is connected to the inlet.
[0052] By configuring the water mist low-temperature mixing component 400, the water mist generated by the dual-fluid nucleator 100 mixes with the cold air generated by the refrigeration component 300 in the water mist low-temperature mixing chamber. This allows the water mist to rapidly evaporate, condense, and crystallize into small snow crystal clusters. These clusters then adhere to and converge through the snow-condensing screen 220 in the snow-condensing component 200, ultimately forming larger snow crystal clusters. In other words, the snow crystal clusters are formed before entering the snow-condensing component 200, meaning they do not need to form within the snow-condensing component 200. This improves the efficiency of the snow-condensing screen 220 in adhering to and converging snow crystal clusters to form larger clusters, thus improving snow quality and increasing snow yield.
[0053] In some optional embodiments, the inlet of the water mist cryogenic mixing chamber, the dual-fluid nucleator 100, and the housing 210 are all cylindrical. The inner diameter of the water mist cryogenic mixing chamber is larger than the inner diameter of the dual-fluid nucleator 100, and the inner diameter of the water mist cryogenic mixing chamber is larger than the inner diameter of the inlet. The second port 420 is located on the side of the water mist cryogenic mixing assembly 400 near the dual-fluid nucleator 100. This allows the water mist generated by the dual-fluid nucleator 100 to be fully mixed with the cold air generated by the refrigeration assembly 300 in the water mist cryogenic mixing chamber in a timely manner, providing sufficient space and time for the condensation of the water mist, ensuring that the water mist can evaporate, condense, and crystallize to form small snow crystal clusters, thus improving the quality of the snow crystal clusters.
[0054] For example, in this embodiment, the inner diameter of the water mist cryogenic mixing chamber is 2 to 3 times the inner diameter of the dual-fluid nucleator 100, and the inner diameter of the water mist cryogenic mixing chamber is 2 to 3 times the inlet inner diameter of the housing 210.
[0055] For example, the second port 420 in this embodiment can be disposed on the top of the water mist low-temperature mixing component 400 or on the side wall of the water mist low-temperature mixing component 400.
[0056] Optionally, in this embodiment, the first port 410 is threadedly connected to the dual-fluid nucleator 100, the second port 420 is threadedly connected to the refrigeration component 300, and the third port 430 is threadedly connected to the inlet. This improves the reliability, stability, and convenience of the connection between the water mist cryogenic mixing component 400 and the dual-fluid nucleator 100 and the snow condensation component 200, thereby facilitating disassembly, replacement, and maintenance, and improving work efficiency.
[0057] Optionally, in this embodiment, the cooling component 300 is a vortex tube, and the cold air port 310 of the vortex tube is connected to the second port 420, so that the cold air generated by the vortex tube can flow into the water mist low-temperature mixing chamber.
[0058] It should be noted that the vortex tube in this embodiment is a common device on the market. The vortex tube is provided with a cold air port 310, a hot air port 320, and a compressed air port 330. The hot air port 320 is connected to an external heat source collection device, and the compressed air port 330 is used to connect to an air compressor. The specific internal structure and working principle of the vortex tube are conventional designs and will not be described in detail here.
[0059] Optionally, in this embodiment, a temperature and pressure gauge 340 is provided at the cold air port 310 of the refrigeration component 300. The temperature and pressure gauge 340 is used to measure the pressure and temperature of the cold air at the cold air port 310. Specifically, a temperature and pressure gauge 340 is provided at the cold air port 310 of the vortex tube so that operators can read the pressure and temperature of the cold air at the cold air port 310 in real time.
[0060] like Figure 1 As shown, in this embodiment, the snowmaking machine terminal auxiliary device also includes a bracket 500, which is connected to the housing 210. The bracket 500 is used to mount the snow-condensing component 200 on the ground, so that the snow-condensing component 200 can be raised to a certain height, making it convenient to spray snow toward the ground.
[0061] This embodiment also provides a snowmaking system, which includes the aforementioned snowmaking machine terminal auxiliary device. The snow produced by this snowmaking system has high quality, can improve the snow production rate, and save costs.
[0062] Example 2
[0063] like Figure 2 As shown, this embodiment provides a snowmaking machine terminal auxiliary device, the main difference from the first embodiment is that the cooling component 300 is attached to the outer wall of the housing 210.
[0064] In this embodiment, the cooling component 300 is a semiconductor patch 350, which is attached to the outer wall of the housing 210. Through heat transfer between the semiconductor patch 350 and the housing 210, the housing 210 is cooled down, so that the temperature inside the snow condensation component 200 is controlled below the freezing point, thereby improving the efficiency of water mist evaporation and condensation and facilitating the formation of snow crystals.
[0065] Optionally, the semiconductor patch 350 in this embodiment is also called a semiconductor cold plate. It can be configured as a combination of P-type semiconductors and N-type semiconductors commonly found on the market. The semiconductor patch 350 is a conventional device, and its specific structure and working principle will not be described in detail in this embodiment.
[0066] The remaining structures of the snowmaking machine terminal auxiliary device in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.
[0067] This embodiment also provides a snowmaking system, which includes the aforementioned snowmaking machine terminal auxiliary device. The snow produced by this snowmaking system has high quality, can improve the snow production rate, and save costs.
